I would use my illegal access mainly to give me green lights, and divert traffic away so I have some peace and quite. But consider that planes are already flying with the help of computers and the pilots are just as overseers.

Until today I never heard that a criminal/organization was able to crack the autopilot of a commercial airliner or à la Die Hard take over a tower to falsify Input. In the end if we had that technology it would not be as easy as hacking a twitter account with the password: 12345.

But the commercial part will happen a lot faster. So it will be like google if you have the money you will be on the first page or the right customers will drive by your shop…
